ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 281014 - KFD2-SR2-EX1.W.SM Safety Relay Switch Amplifier
This K-System series safety relay switch amplifier provides intrinsic safety for signals originating from hazardous areas. It conditions inputs from NAMUR sensors or mechanical contacts, offering galvanic isolation and converting them into a safe, fail-safe relay output for control systems. Certified for Safety Integrity Level (SIL) 3, it is engineered for critical safety instrumented functions in process automation and emergency shutdown systems.
